Three single-chip load switch ICs, the TCK106AF, TCK107AF and TCK108AF, combine on-resistance ratings down to just 63mΩ and low typical quiescent currents of 110nA with low loss, low standby current and high performance switching characteristics.

The Toshiba CMOS process combines an output transistor and an output driver, enabling the single-chip IC load switches provide a smaller footprint than switches composed of multiple discrete components. This makes them suited to space-sensitive applications. The ICs help reduce power consumption in devices such as industrial tablets, M2M modules and other portable, battery operated equipment, says the company.

Integrated slew rate control drivers and low on-resistance P-ch MOSFETs and N-ch MOSFETs, allow the ICs to reduce system power consumption via power supply distribution or power supply control for each function block. The ICs allow for low-leakage load switching, while maintaining a low on-resistance. All three are housed in a general-purpose SOT-package measuring 2.9 × 2.8 x 1.1mm.
